HI

 

I get this error in the log files of my emby server:

What is here my problem? I don't found any problem. Ok I can't download data in Android emby app. But on Web App it work so I think this is not the problem of this error.

 

I have set up a pfx certificate with password. The browser show my a valide certificate.

It would suggest that some client device is trying to use an older ssl protocol.

Thank you. I use only the newest android Mobile App and the web Client

Read through the thread below. The error could be thrown for more than one reason and a couple of them are covered in there.
